Hudbay's Lalor Exploration Yields More Precious Metal Intersections

May 05, 2009

Lalor drill hole locations, assay results, and map, as well as a complete historical listing of holes, collars, intersections and assays and the September 19, 2008 NI 43-101 technical report, are available on HudBay's website: www.hudbayminerals.com

TORONTO, ONTARIO, May 5, 2009 (Marketwire via COMTEX News Network) -- HudBay Minerals Inc. ("HudBay", "the company") (TSX:HBM) continues to add significant precious metal intersections at its 100% owned Lalor deposit in the Flin Flon Greenstone Belt. Highlights of those results include DUB 230 grading 23.11 g/t Au over 8.75 m, DUB234 grading 10.28 g/t Au over 13.00 m, and DUB204W03 grading 6.68 g/t Au over 24.44 m. As a result of ongoing drilling results, HudBay plans to spend an additional $6.1 million on Lalor exploration in 2009. The originally projected expenditure for 2009 was $6.9 million.

"I am very pleased with the continuing excellent Lalor precious metal intersections," said Peter R. Jones, HudBay's chief executive officer. "This project, in terms of both base and precious metals, is a key opportunity for organic growth."

The ongoing Lalor exploration program will focus on extensions to the previously identified footwall gold zone as well as improving knowledge about the continuity within the zone. The $6.1 million additional expenditure is expected to provide 10 new holes from surface and 16 wedges holes.

Drilling to date is approximately 115,000 metres in 86 drill holes and 46 wedges. Drilling to date not included in the September 19, 2009 NI 43-101 technical report is approximately 63,000 metres from 48 holes and 39 wedges.

Drilling has also continued to test the zinc rich massive sulphide zones #10 and #20 aimed at upgrading the Inferred Resource to an Indicated Resource.

The zone coding in the above table is the same as the September 19, 2008 NI 43-101 report.

Next steps

Scoping studies are continuing on the Lalor deposit to identify access alternatives, development and mining methods, as well as potential production capacity and concentration options. The additional 2009 exploration program will focus on the precious metal zones and is expected to enhance the value of the deposit.

About Lalor

The Lalor deposit is located in the Chisel Basin of the Flin Flon Greenstone Belt. It has an Indicated Resource of 3.4 MT 1.9g/t Au, 20.5 g/t Ag, 0.71%Cu, 8.82% Zn, and an Inferred Resource of 13.2MT 2.9g/t Au, 34.1g/t Ag, 0.70%Cu, 8.19% Zn, as stated in the September 19, 2008 technical report. Six drills are currently turning at Lalor, which is approximately 15 km from HudBay's concentrator in Snow Lake, Manitoba. The ongoing exploration and evaluation of the Lalor deposit is a primary focus for the company.

Quality Assurance and Quality Control

Exploration core drilling was either BQ or NQ size. The core was logged and mineralized intersections were marked for sampling and assaying by geologists and geotechnicians employed by HudBay's Hudson Bay Exploration and Development Company Limited (HBED) subsidiary. The marked intersections or intervals were sawn in half by a diamond saw and one half of the core was placed in plastic bags and tagged with unique sample numbers, while the second half was returned to the core box and stored. Each bagged core sample was transported to HudBay's Hudson Bay Mining and Smelting Co., Limited subsidiary's assay laboratory in Flin Flon, Manitoba where it was dried, crushed and pulverized and a 250-gram sample was prepared for assaying. From each 250 gram sample 0.25 grams was removed and leached in aqua regia and analyzed by ICP-AES for Ag, Cu, Zn, As, Pb, Ni and Fe. Also from the 250-gram sample, 15 grams was removed for gold determination by fire assaying with Atomic Absorption finish.

Assaying integrity is monitored internally with a quality control program, which includes the use of assay sample standards, blanks, duplicates and repeats and externally through national and international programs. In addition, within each group of 20 core samples, one core sample has a second 250 gram split collected for check assaying at Acme Analytical Laboratories Ltd. in Vancouver, B.C. This news release provides core lengths and additionally where indicated, calculated vertical thickness of mineralization intersected. True widths are not provided. Where metal assays are provided for intersections they are either a single assay of a sample of the entire intersection length or a composite of assays calculated from interval weighted assays over the intersection length.
